How do seismic waves travel through the Earth?
Video lecture describing speeds and paths of different seismic waves within Earth from an earthquake to a distant seismic station. P & S waves travel through the Earth; Surface waves travel around the perimeter of the Earth.
P Waves: Compressional waves that travel through the Earth. Fastest waves. S Waves: Shear waves travel through the solid part of the Earth. Slower than P waves. Surface Waves: Love & Rayleigh waves travel along the surface of the Earth and are the last to reach distant seismic stations.
